And the Al-Mighty created man (Bereishis 1:27)
This was the order of the Creation of man over the twelve hours of the day:
Hour 1: The Al-Mighty gathered dust from all the edges of the world to one place (in order that wherever man would be buried, his flesh and bones would turn back into dust).
Hour 2: He made from this dust a bodily form.
Hour 3: He stretched man's limbs from this bodily form.
Hour 4: He blew in the Neshamah.
Hour 5: He stood man on his feet.
Hour 6: Odom gave names to all the living creatures.
Hour 7: Chava was given to Odom as a partner.
Hour 8: Kayin and Hevel were born, together with their twin sisters.
Hour 9: Odom was told not to eat from the Eitz HaDaas (Tree of Knowledge).
Hour 10: Odom transgressed this commandment and ate of the fruit.
Hour 11: Odom was judged and his sentence was that he be banished from Gan Aiden (Garden of Eden).
Hour 12: He was sent out of Gan Aiden to Har HaMoriah (Mount Moriah).

And the Al-Mighty saw all that He had made and behold, it was very good (Bereishis 1:31)
The Yalkut states on this posuk, "And behold it was good" refers to the Angel of Life. "Very" refers to the Angel of Death. Hidden in this Medrash is the secret to a life of happiness. If a person is happy with his portion and says, "This is good" about all that happens in his life, he then merits a life of fulfillment. However, if he is seeking the "very", the extras, his life is not life. It is death. There is no limit to the extras. A person doesn't die with even half of his desires fulfilled. Chazal say Jealousy and desire drive a person out of this world. He is considered as if he is dead.

And the Al-mighty blessed the seventh day and sanctified it (Bereishis 2:3)
How foolish are those people who lack faith in Hashem. They delay bringing in the Shabbos and they hasten its departure. The six days of the week draw sustenance from the curse that was given to Odom HaRishon, the first man, "From the sweat of your brow you will earn your livelihood" (Bereishis 3:19). Only Shabbos was excluded from this curse. HaKodosh Boruch Hu, the Holy One Blessed is He, Himself, with His glory, blessed the Shabbos and sanctified it. Those who are intelligent hasten the entrance of Shabbos to receive its blessing and they delay its departure so they don't re-enter the curse of the six days of the week so quickly. The fools reverse the order. They delay entering this state of blessing and are quick to leave it in order to enter the cursed state of the six days of the week! Fortunate is the one who merits to understand this, to hasten the coming of the Shabbos and to delay its departure in order to receive the blessing of Hashem which comes automatically to those who accept the Shabbos.

From the fruit of the ground (Bereishis 4:3)
Kayin should have brought Bikkurim from the fruits of one of the the seven species. The posuk is telling us, however, about his cheapness and miserliness for he was a man with a stingy eye. The posuk doesn't say, "From the first of the fruits of the ground". It says, "From the fruits of the ground", from the least desirable. They were flax seeds, like Chazal say. The posukim teach us that this was an action of a miser. The posuk is very brief regarding Kayin's korban, which was not accepted. A more elaborate description is used when referring to Hevel's korban, which was accepted. The posuk regarding Hevel's korban (Bereishis 4:4) says, "From the firstborn of his flock and from their fattest". Hevel brought the firstborn from something which is fit to be a korban, sheep. Kayin brought produce. Produce is not fit to be a korban and he didn't even bring from the first fruits, he brought from the least desirable fruits. The Medrash compares Kayin to a servant who eats the choicest fruits and serves the king the leftovers.
